TO ALL WHOM IT MAY CONCERN:

Be it known that I, OSCAR T. POTTER, of Scott, in the county of Cortland, undStutel of New York, have invented certain new and useful improvements in Carriage Jaoksg and do hereby declare that the following is a. full, clear, and exact description thereof, reference being had to the annexed dra-Wings, and the letters of' reference marked thereon, making :t part of this specification.

My jack may be constructed of either wood Or metal, and of sizes to suit the diierent vehicles.

a represents the standard, which is provided with suitable ears, :c :11, at its top, and to which is hinged the arm b: It willbe'seen that this arm' has a flange, o, at'its bottom, to efeetualiy connect it between the ears at the top ofthe standard. The upper end of this arm is forked, d, as shown, fork the purpose of allowing it to catch under the axle or other suite-ble portion of the. vehicle. This arm has a. crooked handle, m, upon one side, which is secured at about the centre of the said arm and extends below the hinge, so that the crook will lie against the standard-and keep the two parts in a vertical position. Two or more forks may be formed upon the end of the arm, as may be required. The operation Of this device is quite similar to those in use.

Figure 1 shows the fork in the uct of raising the Wagon; while. 'I

lil'igure 2 shows the position of tliejack when the wagon is raised. Y

What I claim' as new, and desire to secure by Letters Patent, isv The arrangement of the arm b', with its fork d, and crooked lever m, inv combination with the standard a,

when used as and for the purposes set forth. Y

OSCAR T. POTTER.
